Application filed Apri15, 1919. Serial No. 287,810.

To all whom t may concern.'

Be itknown that l, JosErI-I Grrnnnm'CAR-V RIER, a subject of the King of Great Britain, residing at Chicoutimi, Province of Quebec, Canada, have yinvented certain .new and useful Improvements fin 'Pulp-Machines; and

` I do hereby declare that'the following is a Jfull, clear, and exact description of the invention, such as will enable )others skilled in the art to which it appertains to make and use the same.

The present invention relates to pulp machines generallyknown as ground wood sulite v.wet machines wherein the woodpulp is conveyed on a suitable screen to collecting rollers. The woodpulp as-1t collects upon these rollers has'to be severed therefrom and heretofore it has been severed by hand or automatically operating cutters, but such devices have proven very unsatisfactory due to the fact that the laps or 'sheets of woodpulp are not cut in uni'formlength, or the cutting has been so inaccurate as 'to cause the collected sheets of woodpulp to :be again deposited on thescreen where they repeated This invention pertains more particularlyto an attachment `for such pulp machines whereby the woodpulp inthe form of sheets'may be automatiy cally severed and removed from the receiving roller o'ti the .machine when a pre-determined thickness o'f stock has been collectedv upon said receiving roller.

An object ofthe present invention is' to provide an improved attachment oit this character which will automatically and 'vetcctively cut'thewoodpulp into sheets of lpre-determined length and thickness.

nother objectof theinvention resides in the provision of means for ad]ust1ng the blades and associated mechanisms, with'rel spect .to the pulpaccumulating roller and providing for the positive return to normal position of the said mechanisms. .n n

A still further object of the invention contemplates the simultaneous ycutting ot' the accumulated pulp on the gathering roller andthe continuous pulp sheetand uniting the severed pulpV sheet with the iiiiislied product after the cutting operation.

A `further object ofthe present invention is to provide anattachment of this character which may be easily and readily applied to lany pulp machine now in l.general use and one which wouldbe strong, durable and eliicien't in use, and which would also `be simple and accurate in operation.

lith the above and other objects in View which will hereinafter appear as the description continues, the invention consists of the novel `features of construction, combination and formation of parts as `will be hereinafter more fully described and lparticularly pointed out "in the appended claims. l

In the accompanying drawings has been shown a simple and lpreferred yform 'of the invention, it being, however, understood that .no limitation is necessarily made to the precise structural detailsiherein exhibited, but the right is hereby reserved to any changes, alterations or `modifications to which recourse maybe had that come with- `in they scope of the'claims without depart- Hing from the spiritv of the invention or sacrificing the eiliciency of the same.

Referring new more particularly to the accompanying drawings wherein like and corresponding parts are designated by similar reference characters throughout the several views.

The pulp machine as llustratcd in the drawings consists of a main iti-aine compriselevational view of the `ing side supports 1 and 2 which are specilically connected by a. plurality oit bars, as shown7 and which serve to bracethe saine, and mounted upon these frames 1 and 2 are the supplemental frames 3. Journaled within. suitable bearings carried by the frames' 1 and 9 is a felt roller el and arranged above this felt roller fl and having contactingengagement therewith is a pulp'collecting or receiving roller 5, provided with the later ally `extending stub shafts 6. Also joui naled within suitable beariiigs carried by the frames 1 and f2, are the idler rollers T, over which passes a continuous felt conveyer 8. This telt conveyor' extends over the idler 7, as well. as the felt roller l and one portion thereoic travels through a suitable collecting reservoir or screen, not shown, whereby the woodpulp contained within ,Said reservoir is collected by this iielt conveyer 8, in a thin sheet as indicated by the numeral 9, where it is conveyed between the rollers 4l and 5. As this continuous sheet ot woodpulp is being fed between the rollers 4f and 5, it will be collected upon the periphery of the collecting roller As Vthis woodpulp is collected' upon the receiving roller 5, its thickness will gradually increase i until it has obtained a thickness as indicated by the numeral 10 in Fig. 2l. Slidably mounted within oppesitely disposed vertical channels in the 'frames 3, are the bearing blocks 11 on the uppersurtaces et which are connected the lower ends of the coil springs 12 while the upper ends thereof' are connected to the adjusting screws 13 which carry the handles 1st. These bearing bloczs 1.1 rest upon the stub shafts 6, so that the tension upon these stub shafts and consequently the receiving` roller 5 maybe. regulated as desired. As thus iar described the machine is substantially of the `form new in general use.

As stated in the outset ot the specificaedto engage the teeth tion, the invention relates to an, improved attachment to be applied to such machines for the purpose of automatically severing the collected sheets of woodpulp which are of predetermined thickness indicated by the numeral 10, and to cut these sheets when this pre-determined thickness has been ob tained into'pre-determined lengths. Journaled within a bearing -21 secured to the frame 3 in any suitable manner is a frame consisting of a stationary section 15 and an adjustable section 1G which are connected through the slot and bolt connections 1T, and an adjusting screw connection 1S is provided whereby the adjustment may be manu ally regulated to the degree desired. The upper end oi? the section 15 is provided with a bearing 19, having keyed therein one end oit a shaft Q0 and the opposite end ot this shait 20 is mounted within the bearing 21.. Rigidly connected to this shalt Q0 are the sleeves 22, carrying a depending 'SCi-aine or knife holder. The lower end et this :frame 23 is provided with an angular [lange 24 and bolts or rivets 25 pass through apervturcs in this flange and a similar `flange formed on the knife blade 26. This severing means or knife blade 26 is normally retained out of contact with the roller 6 dur-- ing the accumulating period and is intermittently inoperative, but when the wool pulp attains a predetermined thickness upon this roller 5, the knife 26 is automatiH cally set into operation, whereby the woodpulp will be severed and permitted to drop from the roller and rest upon a suitable table or support 2T. Carried by one el the stub shafts (i ot the collection roller is a pulK ley 2S having a parallel smooth flange 29, which is concentric with the shalt (l, and this parallel flange 29 provided with a collntersunk recess 3() in which is wedged a block 81, having segmental teeth 3Q tornied in the outer face thereof. This block Si is likewise retained in position by inea-ns ot one ofthe bolts 33 which latter serve to secure the pulleys 2S to the ends ol.l the receiving roller 5. The lower end ot the adjustable section 1G of the knite support is provided with an enlarged portion Bet having an alining opening :formed therein in which rests the pulley 28. Iivotallycow nected as at 36 to this enlarged portion 3l, is an'arrn 37, having an enlarged outer i'rcc end 38 which acts as a weight so as to cause the" lower face ol' this arm 23T to rest upon the outer peripheryot the flange 29. The lower .face of, this arm 37 is j )rovided with a series of ratchet teeth 39, which are adapt 32 of the pulley The smooth portion 10 Voi the lower face oiE this arm 39 rests upon the outer flange 29 ofthis pulley when the receiving roller 5 is in its lowermost position, but when the .voodpulp accumulates upon the roller 5 and its thickness increases, the roller 5 will be shown in Fig. 3, where `it will engage the woodpulp upon the roller 5 and sever the same. AThe woodpulp after it has'v 'been careifully cut in' the manneras shown in Fig..3

will 'be divided substantially intotwo sections, the outerone of which, indicated by the numeral 41, will drop due toits own weight upon thetable 27, and the oppositel section thereof indicated by the numeral 42 will travel between the rollers 4and 5 and subsequently will be deposited upon the table 27. By making the frame 15 of two adjustable sections it is obvious that the cutting blade 26 'may be caused to swing into operative position when the various desired thicknesses of` pulp have accumulated upon the receiving yroller 5. The desired thickness being pre-determined the section 15 of' this frame may be adjusted to the right position so as Vto cause the rblade 26 `to be operated'whenV this pre-determined thickness of ywoodpulp has adhered to the roller 5. The continuous 'sheetiof woodpulp indicated by the numeral 9 is fed to the collectingiollerand whenfthe woodpulp has been. cut upon this roller, .it is desirous to cut the.' feeding sheet 9 at. the same time, so

l as to only feed between the rollers 4 and5 va sheet of woodpulp which will terminate with the end 42 of the woodpulp 'collected upon the receiving roller, whereby rthe sheet of severed woodpulp' will have the saine thickness throughout its length. To cut this sheet -9 I have providedl another cutting blade 43V and this blade 43 is secured within a irame- 44carriedfby a rocker shaft 45.

Suitably mounted upon the' frames 3 are the rearwardly 'extending rods 46 andy 47, each oi' which having secured thereto abearing block48, and journaled within these bearing blocks 48 is 'the rocker shaft 45. Carried by the rods 46 and 47 are the dependy ing adjustable but rigidly 'held links 49, and ,f slidably mounted within the links 49 'carj Hried by the rod 47 is a rod 50, and this rod 50 has connected thereto an adjustable block 51. Keyed to one end of thisrocker shaft is a sleeve 52 liaving'a depending weight 54 which normally holds the cutting weight 43 in the position' asshownin Fig. 2. ivet'ally mounted uponthe outer face of this sleeve 52 is a pawl 55 having one end therethe bracket 59.

. roller of adapted ktoproject within' the travel of the lblock 51 and its opposite end adapted to engage the projections 56 carried `by 'the sleeve 52. .When 4this block 51 travels in the 'direction of the varrow as shown in Fig. 4' it willstrike against'this pawl 55and the pawl engaged in the projection 56, ywill cause the rocker shaft 45 to oscillate and cause the rblade 43 to assume the position as better shown in Fig. 3 Vwhere vv'it will sever the continuous-sheet ofwoodpulp. Formed integral with the enlarged portion 34 of the frame 16, is a'weight 57, rwhich normally holds the frame 15and'the rocker shaft 20 in the position as better shown inlFigs. 2 and 4, whereby ,the blade 26 will be held out oi contact with the woodpulp and will always be ycausedv to return vto this lnormal lor inoperative position. The rod-is connectved to this weight l57 through a rod 58, so

that whenv the frame 15 is caused to move,

Vthe rod 50 Awill also be carried therewith yand in tuin the blades 43 and 26 will be jointlyv set inoperative position, whereby .they will severthe woodpulp at the same time. Carried by each of the frames 3 are the brackets 59 and these brackets 59 'have mounted therein a threaded rod 60. Adapted to travel upon this threaded rod 60 isa sleeve 61 of a bracket'v62. f The innerr ends of the rods 46 and 47 may be retained within the sleeve 62 by imeans of the bolts 63, and

by rotating the screw 60 the frame` 62 'as Vwell as the rods 47,-and 48 may be vertically adjusted so as to adjust theblade 43 to the desired height. ,'The brackets 62'are provvided .with dependingportions 54 and ex- "tending tlirouglitlie slots 65,y formed Awithin these depending portions 64 is a bolt-66and this bolt 66 is inthreadeil engagement with F rom this yconstruction it is obvious that'the brackets 62 may be adjusted and locked in this usted. position by means of the lbolts 66.

Freni the foregoing it will be obvious that*VK the felt conveyer 8v will cause the-woodpulp to be collected thereupon in l:a continuous sheet as indicated by thelnumeral) andI this sheet of woodpulp is fed between the rollers 4 and 5 `in the usual manner. The roller 4t maybe connected with a'suitable sourcefof power so as to Vcause thesame to revolve con tinuously in one direction, and as the yreceiving i'oller 5 frictionally engagesthe" felt 8 it will also be caused to revolve. woodpulp travels between the rollers 4 and 5 it will be collected upon the receiving woodpulp desired upon this receiving roller may be vascertained 'and the frame 16 may be so` adjustedthat when this pre-determinedthickness of woodpulp upon the roller 5 has been obtained.. the severing mechanism will be set into operation. When the woodpulp has been collected upon As the 'y -ioo *ros

i'ie

A pre-determined thickness of the the roller 5 in this pre-determined thickness the roller 5 will be caused to raise, and in so raising the ratchet teeth 32 will be brought into engagement with the ratchet teeth of the lever 39 of the lever 37, and as this roller 5 is continually rotating the lever 37 will be carried a short distance in a rearward direction with the pulley 28, thereby swingingthe frame 15 and the rocker shaft 20 so that the blade 26 will engage the w0od `pulp upon the roller 5 for severing this woodpulp and forming a single sheet. Then this frame 15 is moved into rearward direction the rod 50 will also be caused to move ina rearward direction as it is con nected to this frame 15 through the link 58. The block 51 will engage the pawl 55, and in turnthe rocker shaft 45 will be oscillated so as to bring the blade 43 into cutting engagement with the-woodpulp indicated by the numeral 9, thereby severing this continuous sheet of woodpulp so that the por tion 42 from the woodpulp which has yet to pass through the rollers 4 and 5 will receive this severed sheet 9 of woodpulp so that the section 42 after it has been passed between the rollers 4 and 5 will have the same thickness as the section 41. After this sheet 10 of woodpulp has passed betweenthe rollers 4 and 5 and been deposited upon the table 27 the roller 5 will drop due to its own weight down upon the 'felt conveyer 8. then this roller 5 has been lowered the ratchet teeth 39 will be out of engagement with the ratchet teeth32 by the pulley 28, and the weight 57 will cause the iframe 15 and the blade 26 to return to its normal position. Then the frame 15 has returned to its normal position the 4bar 50 will, be again drawn forward anda block 51 will be permitted to pass by the pivotally supported pawl 55. The weight 54 connected to the rocker shaft 45 will also cause the cutting blade 43 to return to its normal position. Thepulp machine still being in continuous operation will `deliver the sheet 9 again between the rollers 4 and 5 wherein another supply of woodpulp may be accumulated upon the roller 5, and in this manner the woodpulp may be continually .ted to the collecting roller and the sheets 1 0 of woodpulp may be formed having apredetermined thicknessin all its length and a pre-determined length. i

In the modifications illustrated in Figs. 13 to 18 inclusive, I have provided an actuating mechanism .ior blade 26 and the secondary cutting blade 43, embodying to a maximum? degree, simplicity of construction and operation. This mechanism particularly illustrated in Figs. 13 and 14, comprises a stationary section 67 and an adjustable section 68 which are connected through oppositely disposed slot and bolt connecthe said sections.

y thereon.

tions 69 and 70. The upper end of the sta tionary section 67 is provided with a bearing 71, having keyed therein one end of the shaft 20, while the opposite end is keyed in a similar bearing not illustrated, but positioned at the other side of the machine.

The stationary section 67 is provided with an integral outwardly projecting lug 72, which latter lextends through and is capable of adjustment on a vertical plane in the central slot 73 of the section 68. Shoulders 74 are formed `integral with section 68 and are provided with interiorly threaded apertures adapted for reception of the screws 75. These screws 75 have their lower ends in permanent contacting engagement with the lug 72, so that, upon adjustment of same,

the movable section 68 may be raised or low-V ered with respect to the stationary section 67. In this connection it is necessary only to unloosen the bolt 70, extending through Mounted on the stub shaft 6, of the collection roller 5 is a pulley member 76, and the said member is adapted for the reciprocatory motion within the aliningv opening 77 in the enlarged lower portion of the adjustable. section 68. The pulley 76 at its central part is provided with a short spindle 7 8 and a rocking member 79 `is mounted thereon and adapted for limited movement with respect to the said pulley 76. A casing 8O` carrying double annular ball bearingsis'disposed between the spindle 78 and the rocking member 79 and a threaded bolt 81. takes into a recess in the spindle and serves to hold the said rocking member 79 The rocking member `comprises two integrally formed segment shaped elements 82 and 83, and is adapted tor movement on the outer flat surface of the pulley proper. The outer face of the pulley adjoining 'the periphery ofthe same. is provided with a ring 84 which has its ends spaced apart to allow for a limited move ment of the segment element 82 therebetween. The outer peripheral edge of the segmental element 82 is concentric with the axis of roller 5, so that upon the revolution of the roller the segmental element 82 is in intermittent engagement with the down-` wardly Vbowed portion 85 of the-adjustable section 68.

During this contacting engagement, the rocking member 79 1s moved on its pivot and the segment element 82 travels in the.

ring space on the pulley face and therefore, the stationary and adjustable sections 67 and 68 are rocked in unisonl The degree of' the rocking-,movement of the said sections depends upon the size of the opening be` tween the ring ends. i

A weight member 86 is attached to one side of the enlarged lower portion of the adjustable section 68, by bolts passing leither direction.

through lugs 87 arranged on s aid sections and the saidr weight'holds the,V frames and rockershaft'20 in lthe position illustrated' in Fig, l, so that the. blade willbe held outof contact with the woodpulp and'alsoy cause the same to return to normal` or inoperative position thereafter.

As in the preferred form the rod`^88 is connected-'to the weightmember vS6. through a rod 89 andlwhen the frames are caused` to move the rod 8S willfbe carried therewith. A 1od90' extends in aV parallel plane to the rodSS and the same are connected` to ether by depending adjustabley links 91'. {eyed yto one end of the rockershaft carrying the blade'43 not illustrated, is a sleeve 92 ,hav-y ing a depending weight 93, Awhich normally holds the blade-43inpositon as illustrated in Fig. 4. A pawl memberl 94 ispivotally mounted upon'the outer face of the sleeve 92 and has one face adapted kto project rwith` in the travel ofa block 95 on rod 88, and its opposite end to engage the projection 96 carried by theV sleeve 92. W'hen the block'95 y travelsin one direction itv will strike against the pawl Ymember 94:k andthe latter will cause the rocker shaftcarrying thelmife or bladefiS to oscillate and assume an upright or cutting'positionto sever vthe continuous sheet of' fwoodpulp.,y Thel weight. 93 is formed with horizontally extendingarms 97 which arey connected with the collars l98 Aby,

these springs yis, to 'exertsuffi'cient energy to force" the rod 89 downwardly against the j weight memberSG and return theisections 67 andl 68' toA their normal positions.

For the purpose` Voffadjusting the sections 6T`and68 in a horizontal plane with respect to the pulley member f 76, to regulate the contacting engagement jofthe bowed portion S5 with the segmentelement 84, I provide av regulating, member 101, comprising a split collar 102, formed; withzoppositely disposed flanges 103, whichare apertured for a plu rality of bolts 104. These bolts are screwed into apertured flanges 105, f'0rmed on the upper' endof'thestationary member 67, andr in order to shift they above'member on shaft 2 0, it is only necessary to n unloosen the, bolts "104 andra' centrally disposed bolt 106" and withdraw the shaft, key 107.

It is therefore seen that byY thisnovel` construction thev main] blade swinging elements are adjustablel m vertical and horizontal planes with respect to the pulley element andv means are provided for a more positive return to normal position of the actuating mechanism;

It is also apparentthat this attachment willi be automatically'operated while. the pulp machine is in continuous operation and that none ofthe woodpulp which is fed to the receiving rollers isA wasted. The

wood'pulp after it has been formedy in the sheets 10 of the same length` and thickness mayfzthen, bevpresented to a suitable dehydrating press, where the water contained therein may be pressed from the sheets and 26' and 43 will operate in unison.
